Food material cutter

Abstract

The food material cutter of the present invention has a feeding port for feeding a doughnut, titled plates and guiding plates for guiding the fed doughnut, and rotary blades for slicing the guided doughnut in half in the thickness direction. The link mechanism causes the tilt angles of the tilted plates to be increased due to the own weight of the doughnut, and causes the guiding plates to move by an equal distance from the center of the clearance between the respective guiding plates while matching with the thickness of the doughnut. The doughnut-is guided by the titled plates and guiding plates, and falls down to the palette in a state where it is sliced in half in the thickness direction.

What is claimed is: 
     
       1. A food material cutter comprising:
 a guiding means which guides a food material to a sliceable position; and 
 a cutting means having cutting blades for slicing the guided food material, 
 wherein the guiding means is provided with a feeding part into which the food material is to be fed, a pair of opposite guiding plates for guiding the food material fed into the feeding part to the cutting means, and a centering mechanism which moves the guiding plates by an equal distance from the center of the clearance between the respective guiding plates while the respective guiding plates matches with the thickness of the food material due to the own weight of the food material fed from the feeding part, 
 wherein blade edges of the cutting blades are provided so as to pass over the central plane between the guiding plates, and configured so that the food material guided by the guiding plates is cut in half from the center of the thickness direction by means of the cutting blades, 
 wherein the cutting blades comprise a first rotary blade and a second rotary blade which are made rotatable mutually reversely in a direction of rolling in the food material, and are provided on a central plane between the guiding plates, and 
 wherein straight lines formed by projecting rotation trajectories of the first and second rotary blades onto a horizontal plane are in contact or overlap with each other. 
 
     
     
       2. The food material cutter according to  claim 1 , which is provided with an energizing means which energizes the guiding plates to a direction of narrowing the distance between the guiding plates. 
     
     
       3. The food material cutter according to  claim 2 , wherein the energizing means energizes the guiding plates due to the own weight of a weight, the guiding plates and the weight being coupled by the link mechanism. 
     
     
       4. A food material cutter comprising:
 a guiding means which guides a food material to a sliceable position; and 
 a cutting means having cutting blades for slicing the guided food material, 
 wherein the guiding means is provided with a feeding part into which the food material is to be fed, a pair of opposite guiding plates for guiding the food material fed into the feeding part to the cutting means, and a centering mechanism which moves the guiding plates by an equal distance from the center of the clearance between the respective guiding plates while the respective guiding plates matches with the thickness of the food material due to the own weight of the food material fed from the feeding part, 
 wherein blade edges of the cutting blades are provided so as to pass over the central plane between the guiding plates, and configured so that the food material guided by the guiding plates is cut in half from the center of the thickness direction by means of the cutting blades, 
 wherein the feeding part has a pair of tilted plates which are open upward, and is configured so that the space between the lower ends of the respective titled plates widens due to the own weight of the food material, and 
 wherein the titled plates are coupled by a link mechanism and also the tilted plates and the guiding plates are coupled by the link mechanism so that the wider the space is, the greater the moving distance from the center of the clearance between the respective guiding plates is. 
 
     
     
       5. The food material cutter according to  claim 4 , which is provided with an energizing means which energizes the guiding plates to a direction of narrowing the distance between the guiding plates.
